MiniTioune (also called Minituner) is a PC based system for receiving digital TV transmissions on the amateur radio or broadcast bands and can be used to receive DVB-S QPSK transmission from broadcast and amateur TV transmissions with symbol rates (SR) from 30 Msymbols down to 112Ksymbols per second.

The very wide symbol rate range means it is capable of receiving all amateur TV transmissions using DVB-S or DVB-S2 standards, including the Reduced Bandwidth (RB-TV) transmission below 1 Msymbol and the HamTV signals from the ISS.

Hardware

The hardware consists of 3 major components – the Tuner or NIM, the USB interface and power supply components.

When used with the Sharp or Samsung tuner or NIM component, frequency coverage is from 650 MHz through to 2600 MHz. This extended frequency coverage gives greater flexibility when working with up converters from the VHF bands and enables the 10 GHz band, including Es'HailSat-2 down link, to be received on a standard domestic PLL LNB.

The extended range Sharp tuner and pre-programmed USB interface module and a blank PCB are available from the BATC on line shop https://batc.org.uk/shop/hardware-and-kits – all other components are available from normal suppliers.

A zip file containing circuit diagram, layout and build instructions can be downloaded from here.  Please note the “full kit” mentioned in documentation is no longer available.

Software Downloads

The system uses free to download software called "Tutuione" written by F6DZP. The Software is hosted on the VivaDATV forum. You need a log-in to download, but here are the links:

Software Installation

For a step by step guide on how to do this, see the paper written by W6HHC - http://www.w6ze.org/DATV/InstallingMiniTiouner_onWin10.pdf

  • Install the D2XX drivers 2.12.24 found at http://ftdichip.com/Drivers/D2XX.htm. There's a link in the right column for a setup executable. This stage is missing from W6HHC notes.
  • Install the FT2232H USB driver for the MiniTiouner board
  • Inspect the FT2232H USB-controller module (preprogramed by BATC for NIMtuner) for correct internal memory programming
  • Install LAVfilters CODECs and test the HW board and test the DirectShow filters
  • Look in the Minitiouner folder that you've just copied to C:\ for the small program Install_usrc_ax_winXP and run this to install the missing Codec. This is in W6HHC's notes but he doesn't say where to find it.
  • Run the MiniTiouner_v0.5a executable & perhaps adjust the decoder filters being used.

Receive upconverters and filters

As mentioned above, the tuner components (also called NIMs) used in MiniTioune only cover a maximum of 650 to 2600 MHz.

Whilst this is fine for the 23cms (1.3 GHz) and 13cms (2.3 GHz) amateur bands it does not provide coverage of 146 (2mts) and 437 MHz (70cms) where the majority of ATV operation takes place. Therefore we need to use an upconverter in front of the tuner which converts 146 MHz and 437 MHz up to an L band frequency that the MiniTioune will receive.

A separate section on the wiki gives details of these upconverters.
